RTP simulator
Run up to 10,000 crash rounds with the RTP, target and bet you choose. The simulator uses the same Spribe-style geometric distribution as live crash games. Run it a few times to feel the variance: the same settings can give very different sessions.
How the simulator works
Each round, the simulator draws a crash multiplier from a geometric-style distribution: 1 / (1 − U × (RTP / 100)) where U is a uniform random in [0,1). That matches the published Spribe Aviator distribution and most modern crash titles.
If the drawn multiplier is at or above your target, you win (collect target × bet, profit = (target − 1) × bet). Otherwise you lose your stake. The chart shows the running balance round by round, the metrics show the headline stats. Run it three or four times with the same inputs to feel how much variance changes session shape.
What to look for
- Worst drawdown , the gap between your peak and your lowest subsequent point. Bigger than you would expect.
- Longest losing streak , at 1.5× targets a streak of 6+ losses happens roughly once per 200 rounds; at 5× targets it is common to see 30+ losses in a row.
- Final balance variance , same inputs, very different outcomes. Long-run averages are reliable; single sessions are not.
